Why we moved our build to Bazel
+
Posted by Jordan Alvarez on 9 January 2026 · 6 min read
+
+
Our monorepo had grown to 1.4 million lines of code, and a clean CI build took 47 minutes. Incremental builds were unreliable, so engineers ran clean builds out of habit.
+
What we tried first
+
+ - Caching
node_modules between CI runs
+ - Splitting the test suite across 12 shards
+ - Upgrading CI runners to 32 cores
+
+
Each change helped a little, but none fixed the root problem: the build had no accurate dependency graph.
+
Results
+
After the migration, the median CI build takes 6 minutes, and 92% of builds hit the remote cache.
+
Thanks to the developer productivity team for leading the migration.
